Budgeting & Forecasting › The Master Budget

Why is the master budget prepared before the period begins?

Beginner

Answer

It must be ready in advance so it can guide operations, authorize spending, coordinate departments, and serve as the benchmark for control from day one of the period. A budget finalized after the period starts loses its planning and authorization value.
Real-world example The board approves the master budget in December so it governs the year from January 1.
